- Parchment paper
- Cooling rack
Step-by-Step Instructions
Step 1: Prepare the Pan
Preheat your oven to 350°F (175°C).
Grease a 9-inch cake pan and line the bottom with parchment paper.
This helps prevent sticking and makes removal easier after baking.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together:
- Flour
- Baking powder
- Baking soda
- Salt
Set aside.
Combining the dry ingredients first ensures even distribution throughout the batter.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and sugar until light and fluffy.
This usually takes about 3 minutes.
Proper creaming helps create the cake’s airy texture.
Step 4: Add Eggs
Add eggs one at a time.
Beat well after each addition.
Mix in the vanilla extract.
The batter should become smooth and creamy.
Step 5: Add Sourdough Starter
Add the sourdough discard to the mixture.
Mix gently until fully incorporated.
The sourdough adds moisture, flavor, and a slight tang that makes this cake special.
Step 6: Combine Wet and Dry Ingredients
Gradually add the flour mixture to the wet ingredients, alternating with the milk.
Mix only until combined.
Avoid overmixing to keep the cake soft and fluffy.
Step 7: Fill the Pan
Pour the batter into the prepared cake pan.
Smooth the top with a spatula.
Tap the pan lightly on the counter to remove any large air bubbles.
Step 8: Bake
Bake for 35–40 minutes or until the top is golden and a toothpick inserted in the center comes out clean.
The cake should spring back lightly when touched.
Step 9: Cool
Remove from the oven and allow the cake to cool in the pan for 10 minutes.
Transfer to a cooling rack and let cool completely.
